Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance | Quick Check Method | Recommendation |
|---|---|---|---|---|
| CPU module does not boot | Power supply or processor fault | ✅ High | Verify VME backplane voltages and POST indicators | Check chassis power before replacing module |
| Operating system fails to load | Storage device or BIOS issue | ✅ High | Verify SATA/IDE boot device and BIOS settings | Restore boot media if necessary |
| Memory errors | DDR2 SO-DIMM issue | ✅ High | Test memory using diagnostics | Reseat or replace memory module |
| USB or SATA unavailable | ICH7-M configuration fault | ⚠️ Medium | Check BIOS peripheral settings | Verify chipset configuration |
| VME communication failure | Backplane connector issue | ✅ High | Inspect VME connectors and slot | Test module in another chassis |
| System resets unexpectedly | Overheating or unstable power | ⚠️ Medium | Monitor CPU temperature and supply rails | Improve cooling and verify PSU |
| Expansion devices not detected | PCI/PCIe configuration issue | ⚠️ Medium | Review BIOS and hardware configuration | Verify expansion compatibility |
Field Tip: Most reported WES5123-2600 failures are caused by boot media, DDR2 memory, power supply, or VME backplane issues rather than processor hardware. Before replacing the CPU module, verify BIOS settings, test the memory, inspect storage devices, and confirm stable VME power distribution.
